Industry Applications for the Serial Link Adaptor

The 172JNN21032C is designed for industrial environments requiring flexible serial communication. Typical applications include:

• Process Control Systems: Connecting Modicon Momentum controllers to RS485 networks for remote I/O and operator interfaces. The selectable RS232/RS485 port allows adaptation to existing wiring infrastructure.
• Building Automation: Integrating HVAC or lighting control subsystems via serial links, where the lithium battery maintains timekeeping and configuration data for up to five years.
• Material Handling: Enabling communication between conveyors or sorters and a central PLC, with the LED indicator providing immediate status feedback for troubleshooting.

Installation and Setup Guidance

Mount the adaptor securely in a dry, indoor location with ambient temperatures between 0°C and 60°C. Connect the D-shell 9-pin connector for Modbus Plus to your network. Select RS232 or RS485 via the onboard jumper or software setting (refer to the manual). Power is supplied through the I/O base at 5 V DC ±5%. Ensure the current consumption of 700 mA at 12 V DC is within your power budget. The compact dimensions (0.98 x 5.6 x 2.36 inches) facilitate easy DIN-rail or panel mounting.

Maintenance and Reliability

The lithium 2/3 AA battery provides five years of typical life. After a low battery indication at 40°C, plan for replacement within 30 days to avoid data loss. The conformal coating (Humiseal 1A33) protects against moisture and contaminants. Periodic visual inspection of the LED and connections is recommended. The unit withstands vibration up to 1 gn (57–150 Hz) and shock up to ±15 gn, ensuring reliable operation in industrial settings.

Selecting the Right Serial Communication Module for Your Modicon Momentum Platform

When integrating a Modicon Momentum automation platform, reliable serial communication is critical for data exchange and system control. The Schneider Electric 172JNN21032C serves as a dedicated serial link option adaptor, providing a flexible and robust interface for RS232 or RS485 networks. This guide helps you evaluate its key features, applications, and operational considerations to determine if it meets your industrial communication needs.

Compatibility and Integration

This adaptor is part of the Modicon Momentum automation platform. It supports RS232 or RS485 serial links, selectable per application. The single communication port uses a D-shell 9-pin connector for Modbus Plus. Compliance with CSA, NEMA 250 Type 1, and IP20 per IEC 529 ensures integration into standard industrial enclosures. Certifications include UL, CUL, CE, and FM, meeting North American and European requirements.

Selection Guide and Purchasing Advice

When evaluating the 172JNN21032C, confirm your network requires either RS232 or RS485 and that your system voltage matches 5 V DC ±5% via the I/O base. The battery-backed clock drift of ±13 s/day is suitable for time-stamping events. For lifecycle status and availability, contact AutoDCSTech before ordering.
